Rico. 00:15.550 --> 00:18.910 With heaps that one installations of over four thousand. Feet. 00:21.930 --> 00:23.440 Do the normal dry season. 00:24.740 --> 00:28.230 The Rupert Michel when scenic with of war will about a lot of 00:28.230 --> 00:29.760 cubic feet% of the 00:31.500 --> 00:34.860 The rainy season begins. 00:35.380 --> 00:36.430 The trend streak. 00:37.000 --> 00:40.040 Can turn into a raging river them that there is. 00:42.150 --> 00:45.670 This is due to the steep mountain slopes their we've been sold 00:45.670 --> 00:49.720 medal which causes bring them the river's watershed rapidly run 00:49.720 --> 00:53.920 all important for today. It's causing extensive flooding and 00:53.920 --> 00:55.730 damage to this around environment. 00:57.210 --> 01:00.820 The ten one point say as untoward fickle flooding resulting in 01:00.820 --> 01:04.100 immense human suffering and massive property damage. 01:04.910 --> 01:08.090 The soon to be constructed Portuguese day and will provide the 01:08.090 --> 01:11.660 essential protection needed to prevent this catastrophic flooding. 01:13.240 --> 01:16.470 The Portuguese downside lies in the foothills for from the high 01:16.470 --> 01:20.020 first of the central melvins and the long plane of the southern 01:20.020 --> 01:24.460 coast on the Portuguese river approximately four miles northwest 01:24.460 --> 01:25.130 of ponce. 01:26.560 --> 01:30.830 That topography of this area is feeling with steep slopes rising 01:30.830 --> 01:34.680 five to six hundred feet above the river with a heavy role of 01:34.680 --> 01:35.680 timber in brock. 01:36.710 --> 01:40.240 The Portuguese down as the final phase of the Portuguese and 01:40.270 --> 01:44.780 without rivers project authorized by congress in nineteen eighty six. 01:45.500 --> 01:49.470 The total flood control of water supply storage project consists 01:49.470 --> 01:54.530 of over nine miles of travels nineteen drop structures to debris 01:54.530 --> 01:59.000 base SMS with control structures into dams. This reviewers them 01:59.000 --> 02:00.990 that was completed in nineteen ninety two. 02:02.040 --> 02:04.120 And the soon to be constructed Portuguese. Debt. 02:06.950 --> 02:10.530 The Portuguese demos designed as a roller compacted concrete 02:10.760 --> 02:11.720 that Arch their. 02:12.500 --> 02:14.710 With a maximum height of two hundred twenty feet. 02:15.230 --> 02:19.240 Of maximum thickness of one of love of the at the base oppressed 02:19.360 --> 02:23.500 because of thirty five three and a crest linked of twelve hundred 02:23.500 --> 02:24.040 thirty. Three. 02:26.540 --> 02:30.250 At home G Christie's until way one hundred forty three feet wide 02:30.490 --> 02:34.540 is located of the center of the that vendors designed for maximum 02:34.540 --> 02:38.890 skill way discharge of a parchment forty seven thousand cubic feet. 02:39.060 --> 02:39.590 Per second. 02:40.920 --> 02:45.340 The maximum operating area will be seventy two acres with a maximum 02:45.370 --> 02:47.910 we've pool of two hundred fifty acres. 02:49.150 --> 02:52.740 An important part of the Portuguese dam construction will be 02:52.740 --> 02:54.030 the foundation browbeat. 02:55.170 --> 02:58.680 The foundation consist of fractured enjoyed. It metamorphosis 02:58.680 --> 03:02.940 sensed on and conglomerates with prospered in dykes in. Shears. 03:04.870 --> 03:08.310 Can celebrations rallying will be used to from of the foundation 03:08.310 --> 03:12.770 and areas that are we put number of the foundation brave in the infrastructure. 03:13.860 --> 03:17.630 What contact routing will be used to tie together the top are 03:17.630 --> 03:21.280 talking fleet the foundation that the several for their and other 03:21.280 --> 03:25.730 areas that will be excavated and field to remove shears or work 03:25.730 --> 03:28.410 them brought there and we'll we'll foundation. Great. 03:32.800 --> 03:36.230 In addition from grand curtain will be installed longer fall 03:36.230 --> 03:37.130 filed the their. 03:39.000 --> 03:42.970 Three inch minimum diameter holes will be drilled from the foundation 03:42.970 --> 03:46.630 gallery to a maximum depth of one hundred fifty six. Feet. 03:49.780 --> 03:52.920 Grout will be pomp under pressure to end of the holes to fill 03:52.920 --> 03:54.330 the cracks and crevices that's. 03:54.900 --> 03:58.290 The purpose of the grout curtain is to reduce the prawny beloved 03:58.290 --> 04:01.910 even the that there and to assist and the foundation drainage 04:01.940 --> 04:06.140 system introduced five for static pressures incredible areas 04:06.170 --> 04:09.640 that make that there are increasing the integrity of the foundation. 04:10.310 --> 04:13.310 When completed the Portuguese to and will be the first part to 04:13.310 --> 04:17.360 down the constructive into daddy States and its territories using 04:17.360 --> 04:18.960 roller compacted concrete. 04:20.660 --> 04:24.150 An extensive concrete mix design was performed by the U.S. 04:24.180 --> 04:25.500 army corps of engineers. 04:26.060 --> 04:29.380 To establish the mix proportions and the physical and formal 04:29.380 --> 04:30.730 properties of the. Country. 04:34.320 --> 04:37.620 The construction will consist of placing the concrete and one 04:37.620 --> 04:39.310 four players across the. Them. 04:41.580 --> 04:46.100 That utilizing convey years that dump trucks and those rich. 04:48.180 --> 04:51.970 The lingers will be and be contacted using fiber tour rollers. 04:55.500 --> 05:00.530 That. The Portuguese dam project will require approximately three 05:00.530 --> 05:04.300 hundred sixty seven thousand cubic yards of concrete to construct. 05:05.550 --> 05:08.720 Of the features of the them included can take structure on the 05:08.750 --> 05:10.170 upstream face of the their. 05:10.910 --> 05:14.660 About all else with regulating out was down strained of of them. 05:15.190 --> 05:16.810 And depressed access row. 05:19.080 --> 05:21.490 Doing the pudgy designed to the Portuguese them. 05:22.000 --> 05:25.080 The engineers of the Fort jackson build the Street work with 05:25.080 --> 05:26.430 the force port when district. 05:27.710 --> 05:31.770 On the concrete mix design and materials testing jackson of the 05:31.770 --> 05:34.750 Street work with the injuring research and development center 05:34.750 --> 05:36.200 in pittsburgh Mississippi. 05:37.750 --> 05:41.030 The architectural and engineering forum might go marine watson 05:41.030 --> 05:45.040 horrors of was contractor to perform the conduct and that technical review. 05:46.280 --> 05:49.460 Additionally the that of the lovely constructive that of the 05:49.740 --> 05:53.420 upper building environmental review was conducted with you. 05:53.420 --> 05:56.480 So stents of experts from several for districts. 05:58.000 --> 06:01.060 The jacksonville district also work for the poor of engineers 06:01.060 --> 06:04.820 computer aided structural engineering task group caves. 06:05.530 --> 06:09.810 To help develop auction down software tools and design criteria. 06:10.750 --> 06:14.380 The task group was composed of members from the port engineers 06:14.450 --> 06:15.990 and the bureau of. Recollection. 06:18.110 --> 06:21.610 The Portuguese dam project. Sponsors is the department of natural 06:21.610 --> 06:47.990 and environmental resources. That. That. That. That. That. That..
